Terminal Blocks - Accessories - Jumpers

Terminal blocks, also known as terminal boards or strips, are modular electronic components intended for stationary electrical and electronic connections. They are used for secure connection of electrical conductors between terminal blocks without the need for welding. As one of the accessories to terminal blocks, jumpers are a type of connection that provides a link between two terminals. The application of jumpers to terminal blocks and its working principle will be discussed further in this article.

The application field of terminal block jumpers is quite broad, and they can be used in a variety of electrical and electronic projects. For example, it allows a fast and secure connection to a circuit board in the production of electronics. This helps to prevent wires from becoming tangled or loose, leading to errors in the electrical connection. Jumpers also provide support in other applications such as computer network circuits, telecommunication projects, optical fiber network projects, and other electronics production projects.

The working principle of a terminal block jumper is relatively simple. It typically consists of two terminals, each with a crimp end and a wire that is inserted between the two terminals. When the two terminals are connected, usually with a bolt and a nut, a circuit is formed. This allows electricity to flow freely between the two terminals, continuing on into other parts of the circuit.

It is important to correctly install a terminal block jumper, as failing to do so could result in a faulty connection. First, the insulation should be cut from both ends of the jumper, exposing the wire. Then, the wires should be connected to the two terminals, ensuring they are correctly connected in the same direction. Finally, the terminals should be tightened with a bolt and nut to prevent them from moving.

Nowadays, modern terminal block jumpers are made of materials such as plastic or stainless steel. Most of them are designed with standardized wire lengths, though one can usually customize the length to fit their specific application. In order to ensure maximum safety, all manufacturers have their own quality control procedures to minimize the risk of poor quality and weak connections.

In conclusion, terminal block jumpers are used for secure connections between two electrical terminals. The application field is large, and the working principle is rather straightforward. If correctly installed and manufactured, a terminal block jumper can be a reliable electrical component, providing a seamless connection for various projects.
